Indoor air pollution of a new building apartment house is known by the causes largest that Formaldehyde and VOCs flowed out at all kinds of finishing materials etc. In-progress a lot of researchers in order to decrease indoor air pollution by these pollutants. In this study, we inquire into a change of emission rate of each finishing materials after construction by progresses in time. We will derive from a reasonable management way regarding this. Indoor air pollutants from indoor finishing materials like wallpaper, wood flooring, paint, and bond were measured. Validation of small chamber method to determine emission rate of construction material was performed with the passage of time. The construction materials were categorized by their feature and the emission rate of VOCs was determined. On the basis of the measurement results achieved, we can estimate emission characteristic of the pollutant from finishing materials. In the present case of TVOC, detected VOCs is the subject of the study range from n-hexane to n-hexadecane, and there is a somewhat discrepancy with a practice hazard material due to converted total sum of each toluene. So it is need to make a plan to regulate emission intensity of hazardous material individually that is detected a large amount except for non-hazardous or rarely detectable materials. And even if time passes, Toluene is continuously detected. In accordance with, research to decrease emission rate of Toluene is necessary for an indoor air quality improvement of a long term. |
